I have a Air Admittance Valve (AAV) on my soil stack in the loft cavity from my ensuite. A few weeks a go the wastes (toilet, sink, shower) started draining slowly and when i flushed the toilet it drained very slow and then a gurgling sound were coming from the other plug holes.
A friend said that its probably the AAV getting stuck so no air was being let into the soil system. I have just replaced the AAV and the problem is still happening.
Has anyone got any ideas to what else could be wrong?
